Tankless water heater venting?

I'm installing a gas tankless heater. My best venting option is right next to were the gas furnace is venting. What is a safe distance for the vents? I assume if they are to close one could pull exhaust from the other. Thanks for any help. No codes where I live.

It depends on the BTU size of the units and specifically what type of venting each appliance has. There are charts online that will provide guidance and your installation manual probably does as well. This page should get you started.
